Midea E35

Midea error code E35 indicates: Midea Lunar Pro / Heat Pump Inverter & Condenser Tumble Dryer: Diagnostic fault code E35 registered by the microcomputer controller. Inverter heat pump compressor thermal protector cut-out tripped due to excessive temperature (>115°C).

The primary root cause for Midea code E35 is: On Midea appliances engineered with thermodynamic closed heat pump circuit with R134a/R290, dynamic residual moisture sensors, and twin-layer lint filter mesh: Refrigerant undercharge from micro-leak in sealed circuit, blocked heat exchanger airflow, or locked compressor piston Metrological tolerance verification: thermal protector contact opens at 115°C ± 5°C (open circuit > 10 MΩ); continuity 0.0 Ω restored when cooled below 85°C..

To resolve error code E35: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: allow compressor 45 minutes to cool down; test continuity across thermal protector terminals and inspect condenser cleanliness. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Close door and turn cycle knob to 6 o'clock. Press and hold Time and Anti-Crease buttons simultaneously for 5 seconds until 'd01' displays. Press Start/Pause to cycle to error log, then hold Start/Pause for 3 seconds to clear faults and return dial to Off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Midea code E35 persists, the physical component causing On Midea appliances engineered with thermodynamic closed heat pump circuit with R134a/R290, dynamic residual moisture sensors, and twin-layer lint filter mesh: Refrigerant undercharge from micro-leak in sealed circuit, blocked heat exchanger airflow, or locked compressor piston Metrological tolerance verification: thermal protector contact opens at 115°C ± 5°C (open circuit > 10 MΩ); continuity 0.0 Ω restored when cooled below 85°C. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
